                      java.util.Collection collection)

Adds all items from the given collection to this list at the specified index.

addAll in interface java.util.List

Overrides:

addAll in class DefaultFilterLogicList

Parameters:

index - the index in this list to begin inserting elements at

collection - the collection of elements to add to this list

Returns:

TRUE if elements were added to this list

containsAll

public boolean containsAll(java.util.Collection collection)

Returns true if this collection contains all of the elements in the specified collection.

Specified by:

containsAll in interface java.util.Collection

Specified by:

containsAll in interface java.util.List

Overrides:

containsAll in class DefaultFilterLogicList

Parameters:

collection - the collection to be checked for containment in this collection.

Returns:

true if this collection contains all of the elements in the specified collection

Throws:

java.lang.NullPointerException - if the specified collection is null.

See Also:

Collection.containsAll(Collection)

removeAll

public boolean removeAll(java.util.Collection collection)

Removes all this collection's elements that are also contained in the specified collection (optional operation). After this call returns, this collection will contain no elements in common with the specified collection.

Specified by:

removeAll in interface java.util.Collection

Specified by:

removeAll in interface java.util.List

Overrides:

removeAll in class DefaultFilterLogicList

Parameters:

collection - the elements to be removed from this collection.

Returns:

true if this collection changed as a result of the call

Throws:

java.lang.NullPointerException - if the specified collection is null.

See Also:

Collection.remove(Object), Collection.contains(Object), Collection.removeAll(Collection)

remove

public boolean remove(java.lang.Object element)

Removes a single instance of the specified element from this collection, if it is present (optional operation). More formally, removes an element e such that (o==null ? e==null : o.equals(e)), if this collection contains one or more such elements. Returns true if this collection contained the specified element (or equivalently, if this collection changed as a result of the call).

Specified by:

remove in interface java.util.Collection

Specified by:

remove in interface java.util.List

Overrides:

remove in class DefaultFilterLogicList

Parameters:

object - the element to be removed from this collection, if present.

Returns:

true if this collection changed as a result of the call

See Also:

Collection.remove(Object)

add

public boolean add(java.lang.Object element)

Ensures that this collection contains the specified element (optional operation). Returns true if this collection changed as a result of the call. (Returns false if this collection does not permit duplicates and already contains the specified element.)

Collections that support this operation may place limitations on what elements may be added to this collection. In particular, some collections will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. Collection classes should clearly specify in their documentation any restrictions on what elements may be added.

If a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). This preserves the invariant that a collection always contains the specified element after this call returns.

Specified by:

add in interface java.util.Collection

Specified by:

add in interface java.util.List

Overrides:

add in class DefaultFilterLogicList

Parameters:

element - the element whose presence in this collection is to be ensured.

Returns:

true if this collection changed as a result of the call

See Also:

Collection.add(Object)

retainAll

public boolean retainAll(java.util.Collection collection)

Retains only the elements in this collection that are contained in the specified collection (optional operation). In other words, removes from this collection all of its elements that are not contained in the specified collection.

Specified by:

retainAll in interface java.util.Collection

Specified by:

retainAll in interface java.util.List

Overrides:

retainAll in class DefaultFilterLogicList

Parameters:

c - elements to be retained in this collection.

Returns:

true if this collection changed as a result of the call

Throws:

java.lang.NullPointerException - if the specified collection is null.

See Also:

remove(Object), contains(Object), Collection.retainAll(Collection)

addAll

public boolean addAll(java.util.Collection collection)

Adds all of the elements in the specified collection to this collection (optional operation). The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified collection is this collection, and this collection is nonempty.)

Specified by:

addAll in interface java.util.Collection

Specified by:

addAll in interface java.util.List

Overrides:

addAll in class DefaultFilterLogicList

Parameters:

c - elements to be inserted into this collection.

Returns:

true if this collection changed as a result of the call

See Also:

add(Object), Collection.addAll(Collection)

subList

public java.util.List subList(int startIndex,
                              int endIndex)

Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. (If fromIndex and toIndex are equal, the returned list is empty.) The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list operations supported by this list.

The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list. (Structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.)

Specified by:

subList in interface java.util.List

Overrides:

subList in class DefaultFilterLogicList

Parameters:

fromIndex - low endpoint (inclusive) of the subList.

toIndex - high endpoint (exclusive) of the subList.

Returns:

a view of the specified range within this list.

Throws:

java.lang.IndexOutOfBoundsException - for an illegal endpoint index value (fromIndex < 0 || toIndex > size || fromIndex > toIndex).
